*you have to factor by grouping,for more information just ask me*

First, take out 4x from the first two and y from the second:

4x(x+5) + y(x+5).

Then combine the 4x and the y:

(4x+y)(x+5).

That's your answer.

thanks. - can you help me with this one?

*48x^2y+20xz+12xy+5z

First, you should notice that 12*4=48 and 5*4 is 20. So, rearrange a little:

12xy + 48x^2y + 5z + 20xz.

Then, take out 12xy from the first two and 5z from the second two:

12xy(4x+1) + 5z(4x+1).j

Combine:

(12xy+5z)(4x+1).

thank you;please help me with my other problems...
